Description

A kind of novel subland drill
Technical field
The utility model belongs to drill bit field, particularly relates to a kind of novel subland drill.
Background technology
Cutter on brill, drilling machine, rig, can cause hole on workpiece or rock.Xu Chi " Goldbach's Conjecture's oil head ": " in 1956, China's bored material was somewhat nervous, and drill bit is not enough." course of work dig pit operation time, drill bit, with vertical shaft rotary, moves axially simultaneously.Soil is cut under the moment of torsion and responsive to axial force of drill bit, is raveled under the extruding and centrifugal action of working-blade, forms native stream and presses to hole wall, simultaneously along page elevator to earth's surface.When native stream moves to without hole wall stop place, because centrifugal action hack is thrown around hole, complete the process of digging pit.
Drill bit is the cutter that boring is commonly used, drill bit is when holing, mainly through cutter head top, workpiece is cut, by chip area, chip is discharged, if chip can not be discharged very smoothly, the hole inwall bored then can be caused to occur cut, workpiece is even caused to become waste product, during drill bit design, the helical angle of chip area directly affects the speed of its chip removal, the larger chip removal of helical angle is more smooth and easy, but, chip also can be larger to the wearing and tearing of drill bit, helical angle is less, chip removal can be slow, relatively little to bit wear, existing drill bit normally arranges three chip areas, chip area is narrow, so helical angle is usually smaller, chip removal is slow, there is cut in easy causing hole inwall.
The many monoblock casts of drill bit that present market is common, arbitrarily cannot change its external diameter size, therefore, same drill bit cannot drill through the hole of different-diameter.
Utility model content
The technical problems to be solved in the utility model is that solution drill bit cannot drill through the hole of different-diameter, and row cuts inconvenient problem.
For solving the problem, the utility model provides following technical scheme: a kind of novel subland drill, by apex point, drillstock and drill body three part composition, it is characterized in that: one end of described drill body is connected with drillstock, described drill body and drillstock are monolithic molding, the other end of described drill body is connected with apex point, described drill body and apex point are one of the forming structure, described drill body is by drill body head portion and drill body body two parts monolithic molding, the surface in described drill body head portion is hierarchic structure, surface, described drill body head portion is provided with a row and cuts groove, described drill body body is cylindrical structure, described drillstock surface offers positioning groove.
Further, described apex point is by hemisphere and cylinder two parts monolithic molding, and described cylinder length is 2 ~ 3cm, and described hemisphere structure is and apex point front end.
Further, the structure in described drill body head portion is cone, basal diameter is 5 ~ 7cm, the height of the drill body of described conical structure is 7 ~ 10cm, the drill body surface of described cylindrical structure is hierarchic structure, diameter is reduced to top, drill body head portion successively gradually by the bottom in drill body head portion, and the reduction scope of two adjacent diameters is 0.1 ~ 0.3mm.
Further, the structure that described row cuts groove is cuboid groove, and it is vertically arrange on the top of the bottom of drill body head to drill body head portion that described row cuts groove.
Further, the structure of described positioning groove is U-shaped structure, described detent be arranged on drillstock by terminal position.
The beneficial effects of the utility model are as follows:
1, ladder drill body of the present utility model, the positioning groove that the vertical row on the hierarchic structure on surface, drill body head portion, surface, drill body head portion cuts structure, apex point and drillstock is effectively combined, reach the hole that a boring can drill through different-diameter, row cuts unobstructed, and installs firm object;
2, it is vertically arrange on the top of the bottom of drill body head to drill body head portion that row of the present utility model cuts groove.This row cuts structure, effectively broken the cutting produced in boring procedure can be got rid of, avoid broken accumulation of cutting;
3, drillstock of the present utility model rearward end is provided with positioning groove, and this positioning groove structure can firmly be installed, under avoiding appearing at bit operation state, drill bit loosen with come off.
Accompanying drawing explanation
If Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Drawing reference numeral: 1, apex point, 2, drill body head portion, 3, drill body body, 4, drillstock, 5, positioning groove, 6, hierarchic structure, 7, row cuts groove
For making utility model object of the present utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, a kind of novel subland drill, be made up of apex point 1, drillstock 4 and drill body three part, it is characterized in that: one end of drill body is connected with drillstock 4, drill body and drillstock 4 are monolithic molding, the other end of drill body is connected with apex point 1, drill body and apex point 1 are one of the forming structure, and drill body is by drill body head portion 2 and drill body body 3 two parts monolithic molding, and the surface in drill body head portion 2 is hierarchic structure 6, surface, drill body head portion 2 is provided with a row and cuts groove 7, and drill body body 3 is cylindrical structure; Drillstock 4 surface offers positioning groove 5, and apex point 1 is by hemisphere and cylinder two parts monolithic molding, and cylinder length is 2 ~ 3cm, and hemisphere structure is and apex point 1 front end.
The structure in drill body head portion 2 is cone, basal diameter is 5 ~ 7cm, the height of the drill body of conical structure is 7 ~ 10cm, the drill body surface of cylindrical structure is hierarchic structure 6, diameter is reduced to top, drill body head portion 2 successively gradually by the bottom in drill body head portion 2, the reduction scope of two adjacent diameters is 0.1 ~ 0.3mm, and this hierarchic structure 6 can reach the object that a boring can drill through the hole of different-diameter.
